Xen does a shutdown of the emulated PCI network device in pci_unplug_nics. But this just disables the PCI device. The tap device for a given emulated card remains active because nothing closes the file descriptor.
The cmdline for qemu contains something like "-device rtl8139,id=nic0,netdev=net0,mac=00:16:3e:28:f1:ee -netdev type=tap,id=net0,ifname=vif1.0-emu,script=no,downscript=no". I wonder if the missing disable of the tap device is intentional, or just an oversight, or if its just to complicated to get from a "PCIDevice *" to the other end and call the ->cleanup function.
